This app supports parallel track, creeping line, expanding square, sector search, route search, and CAP grids. It is very easy to use: you just fill in the form, and at the press of a button a list of coordinates is calculated that can be copied and pasted into the flight plan field of another app such as Garmin Pilot.

The app is under active development and I will be putting out a new release shortly. I am very curious to hear feedback on what would make this app more useful. Thanks!
